Phytochemical studies on the roots of Hemidesmus indicus resulted in the isolation of six new pentacyclic triterpenes including two oleanenes identified as olean-12-en-21 beta-yl acetate, and olean-12-en-3 alpha-yl acetate, three ursenes characterized as 16(17)-seco-urs-12,20(30)-dien-18 alpha H-3 beta-yl actetate, urs-20(30)-en-18 beta H-3 beta-yl acetate and 16(17)-seco-urs-12,20(30) dien-18-alpha H-3 beta-ol and a lupene formulated us lup-1,12-dien-3-on-21-ol including a known compound, beta-amyrin acetate, on the basis of spectroscopic techniques and chemical means.
